This study aimed to explore sustainable fashion design plans and directions by analyzing Marine Serre’s collection. Previous research was reviewed to derive classifications of the aesthetic characteristics of sustainable fashion design. This classification was then used to analyze the characteristics of the Marine Serre collection. Design analysis was conducted on Marine Serre’s 2018 FW to 2023 SS collections. Marine Serre’s sustainability characteristics are functionality, surprise, handicraft, and inclusion. The results are as follows. First, functionality is the highest among the four characteristics and includes the functionality of movement, the functionality of form, and futurism. This characteristic was observed in the use of all-in-one body suits, pockets, and workwear, showing the will and values of designers who value daily activity. Second, surprise includes the scarcity of materials and the unexpectedness of composition. The value of the clothing is enhanced by the use of scarce materials not typically used in clothing. In addition, Marine Serre is highly regarded for expanding clothing into life by incorporating material upcycling into the theme of the collection. Third, handcrafted features include exaggerated decorations, logo, retro designs, and natural properties, and intentional utilization is differentiated. Marine Serre’s signature pattern suggests a suitable expression for the fabric to use the crescent moon for the season. Fourth, the collection expresses themes of inclusivity and cultural diversity. The results indicate that Marine Serre wants to contribute to a better future characterized by global coexistence.

In response to the global trend of making sustainable development an urgent task, luxury fashion brands actively embrace it in their corporate philosophies and management policies. However, despite the widespread consensus in the related industry and the strong will of companies for the sustainable development of luxury brands, there are still few cases of luxury fashion brands successfully implementing sustainable development. This study examined the impact of the types of message framing on the sustainability marketing of luxury fashion brands, focusing on their effects on perceived message effectiveness, sustainable brand image, and brand attitudes. An online survey was administered to 464 Korean consumers in their 20s to 40s to test the hypotheses. The results showed that perceived effectiveness was higher for negatively framed messages (loss) than for their positive counterparts (gain). The types of message framing did not significantly affect sustainable brand messages, and no significant difference in perceived brand image was found, regardless of message type. Perceived message effectiveness exerted a significant positive effect on sustainable brand image, and such an image had a significant positive effect on brand attitudes. The results provide implications for related research and practical implications for the development of competitive sustainability marketing strategies for luxury fashion—an industry still in its infancy.
